In any case, due to each - expansion circuit and The parallel-connected wheel-out circuits are synchronized under the control of the η-phase PWM control circuit. Therefore, the current drawn from the wheel-in power supply will be shared by each expansion circuit and the parallel-connected wheel-out stage circuit. This means that each expansion circuit and the parallel output stage circuit will be able to co-load a larger current than in the case where there is no expansion circuit in the past. Therefore, when the load needs to be supplied with a larger current, it is only necessary to boost the input. The current input by the power supply is sufficient, and the number of phases is not required at all. [Embodiment] In the first figure, a block diagram of a multi-phase DC-to-DC power converter with an expansion circuit is shown to illustrate the present invention. Technical content and appeal benefits. More specifically, the multi-phase DC-to-DC power converter with extended circuit includes a main module (丄), an expansion module (2), And - the power output (3). The main module (work) includes an η phase-cut control circuit (10) and n output stage circuits (丄丄). The n-phase pwM control circuit (1 〇) includes a N-phase pwM controller (丄〇丄), n drivers (1 〇 2 ), and a voltage detector (丄〇3), except that the structural and operational principles of this injury are compared with the four phases described in the prior art. The pwM controller (9), the driver (8), and the voltage debt detector (5) are the same, and the capacity is not 1307206. In any case, the 'per-output stage circuit (n) y is fixedly connected to an output of the η_Μ control circuit (1). The actuator circuit (11) is connected to the output of a drive output stage circuit (11) (11 I is connected to the power output (3), and under the control of the η phase PWM control circuit 1), that is, The driver (1 0 2 ) controls the 'input power supply Vln' to a target power supply one. The power supply V〇Ut is the power demand corresponding to the load (ie, 4), and is supplied to the load via the power output (3). The expansion module (2) is an expansion circuit (20) that connects the output stages (1 1 ) in a one-to-one manner. Each expansion circuit (2 〇) is under the control of the "eye PWM control 1", that is, under the cooperation of the drivers (1 0 2 ) and the parallel connection of the output stage circuits (11) The current input by the input power source Vin. 4 Since the structure and operation principle of each output stage circuit (11) is completely in view of the output stage circuit (7) described in the prior art, that is, each output and circuit (11) ) includes a high-side electronic switch and a low-side electronic 1 (four) la - high-speed switch to the 'one end of the choke system ^ ^ low-side electronic switch, a resistor is connected to the anti-flow The other part of the circle—@, IV ^ 鲕 and one capacitor is grounded at one end, and the other end is connected to the other of the resistor. m. The specific structure of the 'mother expansion circuit (2 0) is 1307206 1307206 Any of the several types described later may be used. The first type is that each expansion circuit (2 η, 椹山, 2〇) is opened by only one electron 'this electronic open relationship is parallel The corresponding two-stage electronic switch of the step-out circuit u. The two types of the brother are each The charging circuit (2 〇) is also a low-side electronic switch that is only connected to the corresponding output stage rabbit road (1 1 ) by only one circuit = (four) into two. The two types are each expansion circuit. (2Q) is composed of two electronic switches, and an electronic switch to a $ _ pair of Jianlian in the corresponding 3,: 'road (11) high-speed switch pair, and the phase switch switch pair. The fourth type is the output stage circuit (1Γ) of each _ 撼 ( (20) is the same as the parallel connection by the mother expansion circuit (2 〇) is the output stage of the parallel corresponding (4) by the (10) TM control circuit The control of (1), =, each expansion circuit (2〇) will be connected to the output stage circuit in parallel! 2) Synchronous operation. For example, the electronic switch on the side of the electronic switch in this first type is synchronously turned on. In the closing and synchronization of the high-side electronic switch, m ^, the electronic opening and closing of the electronic switch in the three types of 5 Haidi and the expansion circuit of the high-speed switching material (2〇)::: open. In the fourth type, the (5) catch switch pair will be replaced with the output stage circuit 1307206. The replacement page (1 1 ) The high-speed switch is the same as the cow 2]-.
